2000 years ago Jesus spoke about such teachers who think they are the only ones who can explain the Bible. Today people should be aware that it is the Scriptures itself that can explain everything and that it is Jeshua, Jesus Christ, whom we should follow as the most perfect teacher.
We should not be afraid to do research outside of the Bible. There are still many other things to be found, by doing so, that Jehovah’s people have yet to learn. To stop researching our Faith would be a big mistake. If we have “The Truth” than there is nothing to fear from such investigations. The trinitarians who say there is only one Bible the right one are giving several reasons for atheists and people against God to have enough proof to show them they are wrong also in their belief of God, because their sayings or words even do not match the bible words or ancient manuscript words and as such those people give a proof there would not exist a God.
